| 摘要 |
The present invention is directed to an isolated DNA molecule encoding a Xanthomonas campestris hypersensitive response elicitor protein or polypeptide. The DNA molecule that encodes such protein has the following uses: imparting disease resistance to plants, enhancing plant growth, controlling insects on plants, imparting stress resistance, imparting post-harvest disease resistance, maximizing the benefit of or overcoming a yield penalty associated with a transgenic trait, inhibiting desiccation of cuttings from ornamental plants, and promoting early flowering of an ornamental plant. These can be achieved by expression of the hypersensitive response elicitor in transgenic plants. Transgenic plants, plants seeds, and cuttings from such transgenic plants are also disclosed. |
